Depending on how old your previous furnace was, you could experience a variety of differences. Furnaces today are developed to give more even and efficient heating than ever before. Modern furnaces also better regulate temperature and air flow, moving more air over the heat exchanger than older furnaces.

Additionally, new furnaces are created to integrate with other high-efficiency HVAC products, such as air conditioners. The air conditioner blowers give your heating system an extra bump so it can deliver cool air around your home efficiently. Special features like variable speed motors will also help reduce noise associated with operating your equipment and easily meet your family's airflow needs.

The Department of Energy recently raised the minimum efficiency levels for air conditioners, heat pumps and packaged units made after Jan. 1, 2015, since heating and cooling contributes significantly to a homes total energy usage. The requirements vary by region, so call Keystone Heating & Air Conditioning Co., Inc for the efficiency standards for Racine.

Keystone Heating & Air Conditioning Co., Inc carries a number of HVAC products with high-efficiency ratings, which can help cut back the amount of energy they require to operate. Aside from picking products that have received Energy Star® certification or achieved high SEER ratings for air conditioners or AFUE ratings for furnaces, you can consider the following:

  • Making certain that your system receives routine maintenance by a trained professional can keep your system operating at its top performance.
  • Zoning systems enable you to heat or cool only certain areas of your home, so you wont have to pay to heat or cool spaces that aren't used.
  • Having a programmable thermostat allows you to set the temperature in your home around your schedule. They can be programmed to give you the comfort you need when you're home and increase or decrease the temperature while you're not around, helping you save on energy bills.

Improving your homes indoor air quality starts with four basic strategies:

  • Poor indoor air quality leaves your home filled with air pollutants floating around. So, to increase IAQ, the first step is to get rid of as many pollutants as possible. You can easily do this by cleaning and vacuuming at least one time during the week, frequently washing linens and storing cleaning products safely.
  • Proper insulation is great for keeping your home warm in the winter and cool in the summer, but it also makes it difficult for airborne pollutants to escape. We have products that help swap stale air for fresh, filtered outside air.
  • Good ventilation and ongoing cleaning are a start, but air filters, germicidal lights and purification systems take your IAQ to the next level by capturing microscopic particles, killing germs and removing particles while destroying chemical vapors.
  • Programmable thermostats will help control the humidity levels and temperature to help stop particles and germs from building up while also keeping your home comfortable.
We advise that you meet with one of the professionals at Keystone Heating & Air Conditioning Co., Inc and have them assess your home and current indoor comfort system. We can help you choose which equipment will be best suited to meet your needs.
Most homeowners believe that air conditioners make your home cooler, but it actually removes the heat from your house, moving the hot air outside. That hot air flows across a cold indoor coil where refrigerant in the lines sends the heat to the coil in your outdoor unit, releasing the heat outside. This process continues until the indoor temperature reaches the temperature you set on your thermostat.
Due to the high amount of energy used by heating and cooling systems, the Department of Energy (DOE) raised the minimum efficiency levels for air conditioners, heat pumps and packaged units manufactured after January 1, 2015. These levels are determined by region and carry varying requirements based on your location. Keystone Heating & Air Conditioning Co., Inc can help answer any questions you may have regarding these minimum requirements and let you know what choices are available when you're looking for a replacement system.
These numbers are located on a nameplate or sticker that is near your systems service panel. The sticker is white with black letters and have both of these numbers located around the top of the sticker. M/N signifies model number while S/N is your serial number.
There are a handful of ways to determine what size system will best suit your home, but the most reliable way to size a system is by having your local Keystone Heating & Air Conditioning Co., Inc technician come out and perform a load calculation. This calculation considers your homes: square footage, insulation value, amount of insulation, and a handful of other factors.
The short answer is Yes. Dirt and other debris can hinder your systems ability to work efficiently. For heat pumps, it is common to have frost or ice on them during the winter, but they also feature defrost controls to ensure they work efficiently in those types of conditions.
Two-stage cooling means that your cooling unit has two levels of operation. When summer is its warmest, the high setting is used, and when its cooler or more mild, it operates on the low setting. Usually, the lower setting is able to take care of your cooling needs, but even when the high setting kicks in, you may not realize it because it can generate such even temperatures for your comfort. This can also mean a quieter cooling system, greater efficiency and better humidity control.
When your cooling unit freezes up, there are a variety of reasons why it could be doing so. The most typical reasons include: dirty filters, low refrigerant, a dirty evaporative coil and a faulty blower motor or relay. A dirty filter is something you can fix as a homeowner, but the others need to be fixed by a professional like those at Keystone Heating & Air Conditioning Co., Inc.

Identifying the best thermostat for your cooling system comes with a lot to think through. Thats why its nice to have such a big variety of choices from Keystone Heating & Air Conditioning Co., Inc. Whether you're in the market for for a programmable or non-programmable thermostat or want to join the smart home trend, there are various thermostats that you have to select from. Some thermostats will depend on what type of heating and cooling system you have, but the team at Keystone Heating & Air Conditioning Co., Inc will be able to help determine what options meet your needs and your budget.
Heat pumps can be a little confusing due to their name, but they actually cover both your heating and cooling needs year-round. When its hot outside it operates like an air conditioner in that it removes heat from your home, but when it cools off, the process gets reversed and it collects heat from outside and brings it inside. Heat pumps are also very efficient, and could produce up to two or three times more heat than the energy it uses.
Of course we think you should also replace your indoor system, but this is why:
  • All outdoor cooling systems have a matching indoor unit that they are created to work with to ensure efficient performance. When they aren't paired with the other part as a whole system, efficiency might be diminished.
  • As with a lot of products, advancements have brought about newer, more efficient ways of doing things. Heating and cooling systems are no different. These developments most importantly include greater heating and cooling efficiency, but also include improved air handling, filtering and noise pollution reduction to name a few.
  • Heating and cooling systems that are more than 10-15 years old normally need to be replaced. Not only do they feature outdated technology, but they are also less efficient than todays models. Buying a new indoor unit at the same time means you'll have a matched system to provide you with even more comfort and efficiency for years to come.
The communication module on your home energy system may send the system's performance records for each module to a website. You should visit this website to learn more about the system's status, energy production and environmental benefits. The site also shows carbon offsets as it happens.
In most regions, rain will be enough to keep the solar modules clean. If you are located in a dusty or industrial area, periodically spraying the modules with water could help improve performance. However, detergents and high-pressure hoses should never be used to clean solar modules.

Heating and cooling can make up a large part of your utility bill. The innovative and high-efficiency heating and air conditioning products available from Keystone Heating & Air Conditioning Co., Inc can help lower these costs. If you're shopping for a new heating or cooling system, look for products with high SEER ratings for air conditioners and AFUE ratings for furnaces. SEER and AFUE are a measure of system efficiency, and the larger the number, the more efficient the product. Besides purchasing a new home comfort system, think about these additional factors:

  1. Is your system consistently maintained? Whether it's a furnace or air conditioner, HVAC systems will operate more efficiently after regular maintenance checks.
  2. Would you benefit from a zoning system? If there are rooms in your home that are rarely used, a zoning system will allow you to heat or cool only the most used areas of your house.
  3. Have you installed a programmable or smart thermostat? According to the U.S. Department of Energy, programmable thermostats may reduce your heating costs by up to 35 percent, and your cooling costs by up to 25 percent.
Zoning systems give you the opportunity to divide areas of your house and control the air differently in each room. Zoning equipment is good for when you have parts of your home that are seldom used or when you and your family are often in disagreement of what the temperature in each area of your home should be. Zoning systems are quiet and efficient, enabling you to have more control over the comfort of your home. Discover more about the equipment available from Keystone Heating & Air Conditioning Co., Inc.
